1. 6. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

   Författare :Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

   Sammanfattning : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. LÄS MER

3. 7. Climate Related Impacts on a Lake : From Physics to Biology

   Författare :Thorsten Blenckner; Rita Adrian; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Ecosystem processes; climate; phytoplankton; NAO; SCI; ice cover; modeling; Biologi; Biology; Biologi; limnologi; Limnology;

   Sammanfattning : Climatic variation and change affect the dynamics of organisms and ecosystem processes. This thesis examines phytoplankton as a target variable to trace climatic impacts on Lake Erken (Sweden) with special emphasis on the spring bloom. LÄS MER

4. 8. Media processes for content production : Studies of structures and climate impacts

   Författare :Malin Picha Edwardsson; Johan Stenberg; Nils Enlund; Åsa Moberg; Gunnar Nygren; KTH; []
   Nyckelord :media; work processes; content production; LCA; climate impacts; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The business environment in which media companies exist today is rapidly changing. Many media companies are in the process of positioning themselves to this ongoing change and to finding their place in the new media landscape. A process of change creates an opportunity to optimize work processes on different levels. LÄS MER

5. 9. Quantifying hydroclimatic change impacts on infectious diseases : Signals and geographies from local to global scale

   Författare :Yan Ma; Georgia Destouni; Zahra Kalantari; Arvid Bring; Rita Colwell; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydroclimatic change; infectious diseases; climate sensitivity; disease geography; quantitative study; scoping review; naturgeografi; Physical Geography;

   Sammanfattning : Hydroclimatic change has the potential to directly or indirectly increase the occurrence and expand or shift the geographical range of infectious diseases. This may pose particular threats in the Nordic-Arctic Region, where warming is more rapid than in other parts of the world, but the climate sensitivities of various infectious diseases still remain to be investigated in this and other regions.

7. 10. Paleoclimate and seasonality on Sumatra during the Late Glacial and Holocene : Insights from biomarkers and climate model simulations

   Författare :Lars Petter Hällberg; Malin Kylander; Frederik Schenk; Rienk Smittenberg; David Naafs; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Holocene; Late Glacial; biomarkers; organic geochemistry; climate model; hydrogen isotopes; stable isotopes; paleoclimate; alkanes; GDGT; brGDGT; H-GDGT; bacterial community shifts; paleothermometry; precipitation reconstruction; peat; geokemi; Geochemistry;

   Sammanfattning : Deep atmospheric convection in the Indo-Pacific Warm Pool (IPWP) is a key driver of the Hadley and Walker Circulations that modulate the Asian-Australian monsoons and the El Niño Southern Oscillation (ENSO). Temperature and rainfall seasonality, i.e. LÄS MER
